Subclasses of Swarm things have Objective C counterparts, and are thus
require manual memory management.  Whenever there are objects that
don't talk directly to Swarm (say instances doing GUI things), then
its cleaner and more portable to benefit from Java's garbage
collection. 

However, when objects do talk to Swarm a lot, those that come and go
during a run should be subclassed, because otherwise pure Java objects
introduce Objective C proxies that will prevent the Java objects from
being dropped by garbage collection (they are added to the directory
that associates Java and Objective C objects).  With subclassed Swarm
objects, the directory entries will be deleted when the object is sent
-drop.  Directory entries and proxies go in globalZone.
